Steroid microbial conversion system is a complex but controllable system with multiple factors involved. In the process of steroid microbial conversion, strain screening and selection is essential to improving productivity and reducing costs. However, good-quality strains need optimal environmental conditions to best play their roles. Therefore, environmental conditions can significantly affect the conversion rate in addition to the quality of the strains utilized. Microbial environment includes physiological and biochemical environment, physical and materialized environment and hydro-mechanical environment. For example, the composition, pH value and dissolved oxygen of culture medium affect the physiological and biochemical environment; gas-liquid interface and liquid-solid interface of culture media affect the physical and materialized environment; scattered and mixed conditions of culture system affect the hydro-mechanical environment. Representative physical factors and their applications in steroid microbial conversion system are briefly reviewed herein.

The surface properties and performance of activated carbon (AC) used for catalytic ozonation were investigated after nitric acid modification (N-AC) and Cu (II)-loaded (N-Cu-AC). The results showed that the nitric acid modification could increase the amount of surface functional groups of AC. As a result, the adsorption capacity and catalytic activity of AC could be improved. The surface functional groups and Cu (II)-loaded of N-Cu-AC showed a synergistic effect on catalytic ozonation, where the catalytic activity of Cu (II)-loaded was more stable. N-Cu-AC was an effective and reusable catalyst for catalytic ozonation. The highest TOC removal efficiency of 58.0% could be achieved when N-Cu-AC was used for 60 min-catalytic ozonation treatment of acid red 3R.

Rolling element bearing is crucial for operation safety of modern mechanical equipment. Its poor damping and heavy load capacity usually makes it degrade faster than the shafts and the gear sets. In this paper, a recently proposed time-frequency (TF) representation tool, named the complete ensemble empirical mode decomposition with adaptive noise (CEEMDAN), is introduced for the TF representation of helicopter bearing degradation data. Totally three sets of sequentially collected accelerometer data were included for the comparison study, with the first two data sets showing no signs of degradation and the third data set corresponds to totally scored bearing rollers. Facilitated by CEEMDAN method, no clear distinction can be observed on the TF plane as for the strong background noises. Thus we previously highlight the bearing signatures using spectral kurtosis (SK), a forth order statistics which is sensitive for impulsive components. Its fast algorithm, called the kurtogram, implements the detection of considerably weak bearing components and suppresses other background components, e.g., gear mesh components. With the preprocessing by kurtogram, the feature information on the TF plane can be easily characterized for the third data set.

As a new environmental-protection technology, large-scale ammonia-based Flue Gas Desulfurization (FGD) requires high control and process technology.

On the grassland highway, the driver is prone to muscle fatigue because of the particularity of its landscape and the linear structure. And vehicle operating system leads to different degree of muscle fatigue. In order to explore the pilot fatigue characteristics in grassland under different operation conversion highway, put forward the fatigue improve measures and improving the quality of driving, I use the real driving test. In this paper, we study the manual and automatic driver’s shoulder muscle fatigue with method of frequency domain analysis through testing the driver, obtaining MF of trapezius muscle in static measurement and the surface electronical signal of the trapezius muscle after 110 minutes’ driving. We devide the drivers into 2 groups (5 drivers in manual group, 5 drivers in automatic group). The results show that the automatic driver’s MF has significantly negative correlation (P =- 0.521) before and after the static test, which suggests automatic driver will be afflicted with shoulder muscle fatigue; The manual drive’s MF before and after the test tends to decrease with time (SlopeMS =- 0.0076, SlopeMD =- 0.0582), which suggests that after test, drivers in manual group are in the right shoulder fatigue, and before test, the decline of MF shows the drivers’ fatigue accumulation. After test, MF of manual and automatic group increases (SlopeAD =- 0.01, SlopeMD =- 0.058), which shows that driving on grassland highway can lead to the driver’s muscle fatigue with the extension of time; and vehicle operating system leads to different degree of muscle fatigue.

The processing of austenite catalytic cryogenic treatment of two components of Cr-W-Mo-V high alloy medium-upper carbon steels and the effect on the retained austenite transformation and tempering hardness were studied in this paper. The results show that, the effect of austenite catalytic cryogenic treatment of Cr-W-Mo-V high alloy medium-upper carbon steel is better than that of direct cryogenic treatment after quenching, and the content of residual austenite reduced to below 5%, and the hardness improved by 1.5HRC than that of conventional quenching and tempering. The retained austenite catalytic temperature of Cr-W-Mo-V high alloy medium-upper carbon steel merely is higher than 10°C~20°C of the temperature for the highest tempering hardness. Catalytic temperature Tc can be determined by experimental method of conventional quenching and tempering of the steel, in which the microstructure feature is precipitation of M3C carbide particle of 0.01μm~0.03μm in martensite matrix, and the content of retained austenite decreases evidently. By cryogenic treatment after the austenite catalyzed the retained austenite of quenching are transformed into more martensite, and in the subsequent tempering processing the original quenching martensite and the martensite from retained austenite transformation almost will form synchronous precipitation hardening. Thus the tempering hardness improves evidently as well.

The influence of Mo and V contents on the microstructure and secondary hardening of 6Cr6W2MoV steel was studied in this paper, and the process factors and the transformation mechanism of the influence results were discussed by phase equilibrium thermodynamic analysis. The results show that, the microstructure of 6Cr6W2MoV steel is uniform and thin, in which the undissolved carbide size after quenching is 0.23μm. In the heating and cooling process of the annealing, the dissolution and precipitation of M23C6↔M6C carbides transformation can be used to carbides distributing uniform refinement. Adding an overmany Mo content will lead to coarsening of carbide particles due to small amplitude of M23C6↔M6C transformation. Adding an overmany V content will appear a small of the bulk MC carbide on the crystallization, so the heterogeneity of carbides is increasing. The tempering hardness of 6Cr6W2MoV steel is 63.5HRC, and when adding an overmany Mo content the maximal hardness arrives to 65HRC. Adding Mo changes the carbide composing, it is conducive to the variety of carbides precipitation strengthening near intermediate temperature and the tempering hardness increasing. When adding an overmany V content the more MC carbide well occupy more amount of C, the tempering temperature dispersion increases too, so the tempering hardness debases deservedly and the highest hardness only reaches HRC60.5.

However, when contact occurred, the RMS and spectrum of AE signal increased obviously and the bandwidth varied exquisitely between 100 KHz and 300 KHz. The real contact time between wheel and workpiece was about 0.5 to 1 ms.

Several geological factors can have a potential effect on dissociation of natural gas hydrate (NGH). It is important to understand their roles in safe exploitation of NGH deposits. This paper accordingly reviews experimental and numerical-modeling researches on impact factors of NGHs dissociation by depressurization. NGHs dissociation usually increases with increasing temperature, permeability, water saturation, thermal conductivity of sediments and depressurization rate of production well, whereas it is reverse for pressure, hydrate saturation, production wells pressure, gas saturation and particle size.

The heterogeneity of NGH deposits, chemical components of pore fluids, relative permeability and capillary pressure can also play a role in NGHs dissociation. However, their influencing mechanisms still need further studies in future.
